COVER Filed May 18, 1931 INVENTOR LOUIS E. LIPscHULTz Patented Nov. 29,1 932 PATENT OFFICE LOUIS E. LIPSGI-IULTZ, OF ST. PAUL, MINNESOTA COVERApplication filed 'May 18, 1931-. Serial No. 538,197.

This invention relates to improvements in covers and has among itsobjects to provide a cheap, efiicient and neat device which may beeasily and quickly applied to reduce air cir- "culation through anautomobile radiator.

Other objects are: to provide a type of fastening device of which themajor portion is hidden; to provide yieldably adjustable attaching meanswhich can be easily inserted in "the radiator openings, and which whenso inserted act automatically to secure the device in operativeposition; and to provide means by which; the attaching meanscan be sopositioned as to facilitate support ofthe cover, during the attachingoperation.

Objects, features and advantagesiof the in-.

vention will be set forth in the description of the drawing forming apart of this applica 2 tion, and in said drawing Figure 1 is a frontview of a radiator with the device applied thereto, the radiator beingof the honeycomb type;

Figure 2 is a plan section on line 2-2 of Figure 1;

Figure viewing its inner side;

Figure 4 is a view illustrating the manner in which the attaching devicecan be manipu- ,lated to provide a finger hold by which the "cover issupported during attachment; 7

Figure -5 is a detail section showing how the wire is pivotallyconnected to the spring...

In the drawing, numeral 1 indicates a sheet of thin material whichserves as a cover; The cover has four pairs of slots, two pair alignedadjacent each of two opposite edges of the sheet. The pairs arerespectively indicated at 2, 3, 4 and 5, and the members of the pairsare indicated 6-7. The outermost members aredesignated 6, and innermost7.

The attaching device or means is, per se, a feature of the invention, aswell as the arrangement of these means in cooperative pairs. Eachfastening means is composed of a single piece of wire connected to coilspring 8. A feature of the invention is the construction by which thewire element is connected to the spring 8, see Figure 5. One end of the'wire is bent upon itself as at 10 to form a swiveling or hingingabutment. The spring 3 is a perspective view of the cover has a numberof constricted terminal coilsll which embrace the wire, with theinnermost c011 abutting the end of the turned portion 10 as a stop forlimiting outward movementof 5 the wire.v

Each coil is connected by one terminal to, the cover as at 13. The wire(connected by one end to the free end of the-spring) is first passedloosely through the inner slot 7, and has an off-setting portion 14formed by firstbending in direction of passage of the wire through theslot and then in an opposite direction, as best shown in Figure 2'. Aportlon 15 lies flatly againstthe outer face of the cover when thedeviceis attached, and the WII'B terminates in an angularly related attachingportion 16 which passes throughthe slot 6. This portion 16 is terminallybent-asat 17 to increase its frictional action, with whatever portion ofthe radiator (or other obect) it is engaged, to resist withdrawal in adirection substantially perpendicularly to the face of the cover.

l/Vhen the device is not attached, the extension 16 engages the innerside of the slot 6, 7

and the off-set portion 14 is spacedfrom the inner side of the slot 7,see Figure 3. When the extension 16 is engaging the end of the slot 6,the spring is under tension.

Another feature of the inventionis the arrangement whereby the wire canbe swung to the position shown in Figure 4. This swingmg motion islimited by means of the terminally bent portion 17, which engages the inner side of the cover as a stop, see Figure 4. (hen the wire ispositioned as shown in F igure 4 with the stop 17 engaging the cover,the off-set portion 14 is disposed as shown, with that bend nearest thespring engaging the inner end of slot 7. As the wire is pulledmanipulates the attaching means to secure the cover to the radiator.

It is conceivable that other forms of spring may be used, and that thewire element may be an integral continuation of the spring instead ofbeing swiveled (or pivoted) as shown in Figure 5. One of the broaderfeatures of the invention relates to the placement of thespring so thatit is hidden when the cover is attached, and another feature relates tothe arrangement of the springs to act in a direction of slot alignment.

This device finds valuable application as a cover for a radiator, but isnot limited to such a use. The term slot refers to any opening in whichthe wire element can move for the purposes herein. Although a wireelement is the cheapest material for the purposes;

. herein, other material may be used.

Preparatory to applying the cover, the wires should be positioned asshown in Fig- 111134 to dispose the portion 15 for engagement by theindex finger to support the cover. Moreover, when the wire is sodisposed, the

operator can more readily grasp the portion 15, by thumb and indexfinger to move the wire axially against the action of thespring 8. Itwill be noted that motions of the hands are in the opposite directions.After registration of the attaching extensions 16 with correspondingopenings and while the springs 8 are under tension,the wires arepushedtoward the radiator and the portions 16 assume the relation shown inFigure 2,

' with the springs 8 under tension to forcefully move the portions 16into frictional abutting engagement with the corresponding tubeinterior. 7

I claim as my invention:

1. A cover element having pairs of slots, covering-attachingmeans onefor each pair, each means comprising a spring secured to the cover, awire attached to the spring and passing through one'slot' and thenthrough the other, and having an attaching portion.

2. A cover element having pairs of slots, cover-attaching means one foreach pair, each means comprising a spring secured to the cover, a wireattached to the spring and passing through one slot and then through theother and having an attaching portion, said wire being adapted to swingupon the cover.

3. A cover element having pairs of slots,

cover-attaching means one for each pair of slots, said means beingcooperatively arranged m pairs, each means comprising a spring securedto the cover, a w1re attached to the spring and passing through one slotand then through the other, and having a portion positioned and adaptedto attachingly engage the device to which the cover is applied. r

4. A cover element having pairs of slots,

cover-attaching means one for each pair of "cured to the cover, a wireattached to the spring and passing through one slot and then through theother'and having an attaching portion, said wire being adapted to swingupon the cover, said wire having means for limiting the degree ofswinging motion, said means also acting for increasing frictionalengagement between the attaching means and the body to which the coveris attached.

6. A cover element having pairs of slots, attaching means one for eachpair, each means com rising a coil spring secured to one side of thecover for elongation in a direction lengthwise of the slots, and a wirepivotally attached to said spring and passing through one slot to theopposite side and then through the other slot and having an attachingportion, said wire being adapted to swing upon the cover and saidattaching portion having means which acts to increase the frictionalengagement of the attaching portion and which also acts as a stop tolimit swinging motion of the wire about its fulcrum, said attachingmeans being ar ranged in pairs with the springs of the members of thepairs acting to urge the attaching portions toward one another.

7 A cover element having pairs of slots, attaching means one for eachpair of slots, each means comprising a spring secured to the cover and awire attached to the spring and passing through one slot to the oppositeside and then through the other slot and having a portion adapted to beinserted in the air circulation passage of a radiator, and lying on thesame side with the spring, and said attaching means being arranged inpairs acting to urge the radiator engaging portions toward one another.

8. A cover element having pairs of slots, cover-attaching means for eachpair, each means comprising a spring secured tothe cover and having anextension which passes through one slot, and then through the other,said extension having means for engaging a body to which the cover isattached.
